The knee is a sturdy joint, but it can dislocate as a result of injury. When this happens, there's a risk of injury to the nerves around the knee. Two nerves that may be injured are the peroneal and tibial nerves. The peroneal nerve has two main parts: one is close to the skin and the other deep in the muscles. Together, they are all called peripheral nerves. Each nerve has two jobs. It receives and sends information about sensation. This is the sensory component of the nerve. It also controls the movement of the leg by giving the muscle messages to contract. This is the motor component. The force of a knee dislocation may be enough to stretch or disrupt nearby nerves. This can result in pain, numbness, loss of motion, and a condition called foot drop. Nerve damage to the muscles that hold or pull the foot up is a cause of foot drop. If a nerve isn't completely destroyed, it can grow back. Nerves regrow at a rate of one millimeter each day or three centimeters each month (about one-half ...
Triglycerides are the most common form of fat found in our bodies. The word triglyceride describes this fat's chemical structure. Its chemical backbone is made up of glyceride (a carbon, oxygen, and hydrogen molecule) with three (tri) attached fatty acid chains. It is also the most common form of fat in vegetable oil and animal fat. Triglycerides are very important as they serve as one of our main energy reserves. They have more than twice the energy as an equivalent amount of carbohydrate or protein. Triglycerides can be absorbed from food through the intestine. Fat cannot freely circulate in the blood, and when we absorb triglycerides or fatty-acids in food, they are repackaged as triglycerides in a fat-protein transporter called a chylomicron. Our body can also make its own triglycerides when we eat more energy than we use, and the energy consumed does not necessarily have to come from fat. The liver can create a fat-protein ...
Neuropathy - distal median nerve
Pain in the wrist or hand that wakes you up at night
May be severe Pain may be felt in other areas, for example in the upper arm (this is called referred pain)
Sensation changes in the thumb and pointer (index), middle, and part of the ring fingers, such as:
Weakness of the hand that causes you to:
Drop things Have difficulty grasping objects
Signs and tests
Your doctor will examine your wrist and ask questions about your medical history. The examination may show decreased sensation in the thumb side of the hand. This is called the "radial" side. There may be weakness of the thumb and difficulty using it to pinch.
Tests that reveal distal median nerve dysfunction may include:
Nerve conduction tests
Tests are ...
